Sample GSM6069163 Query DataSets for GSM6069163
Status Public on Mar 01, 2023
Title WT treated with 50 mg/L Esc 1
Sample type SRA
 
Source name E. coli bacteria
Organism Escherichia coli str. K-12 substr. MG1655
Characteristics genotype: WT
agent: 50 mg/L Esc
Treatment protocol Wild-type strain E. coli K-12 MG1655 was cultured in triplicate in 50 mg/L of each antidepressant for 2 hours, at 25 °C, with shaking 120 rpm.
Growth protocol liquid LB culture at 30 °C
Extracted molecule total RNA
Extraction protocol Bacterial cells were then harvested by centrifugation at 8000 × g for 10 min. Total RNA was extracted using the QIAGEN miRNeasy Mini Kit (QIAGEN, Germany) manufacturer’s protocol with one extra bead-beating step to completely lyse the bacterial cells.
RNA libraries were prepared for sequencing using standard Illumina protocols
 
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina HiSeq 2500
 
Description WTEsc50_2
Data processing Base calling through an integrated primary analysis software called RTA (Real Time Analysis. v1.18).
The NGS QC toolkit (version 2.3.3) was used to treat the raw sequence reads to trim the 3’-end residual adaptors and primers, and the ambiguous characters in the reads were removed. Then, the sequence reads consisting of at least 85% bases were progressively trimmed at the 3’-ends until a quality value ≥ 20 were kept. Downstream analyses were performed using the generated clean reads of no shorter than 75 bp.
The clean reads of each sample were aligned to the E. coli MG1655 reference genome (NC_000913.3) using SeqAlto (version 0.5). Cufflinks (version 2.2.1) was used to calculate the strand-specific coverage for each gene, and to analyze the differential expression in triplicate bacterial cell cultures. The statistical analyses and visualization were conducted using CummeRbund package in R (http://compbio.mit.edu/cummeRbund/).
Gene expression was calculated as fragments per kilobase of a gene per million mapped reads (FPKM), a normalized value generated from the frequency of detection and the length of a given gene.
Assembly: NC_000913.3
